To allcvkom it may concern.

Be it known that I, AUBIN BUQUET a citizen of the United States, and a resident of v Dulac, 1n the parish of Terrebonne and State of Louisiana, have invented a certain new and useful Improvement in Computing- 1cales, of which the following is a specificaion.

My invention relates to improvements in computing scales, and it consists in the combinations, constructions, and arrangements herein described and claimed. An object ofmy invention is to provide an index arm or pointer by means of which the tare Weight of a container is registered is mediately when the container is placed on the scale pan, thereby obviating the necessity of shifting weights to balance the container in order to fill the container with a given net weight of a commodity.

A further object of my invention is to prov1de an indicating arm or pointer having aplurality of radially extending lines which render the reading of the scale much easier.

A further object of my invention is to provide a scale having an arm by means of which the tare weight may be registered, and by means of which the net weight may be indicatedand the selling price instantly observed.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings forming part of this application, in which:

Figure 1 is a face view of a scale having my improved arm embodied therein;

Fig. 2 is a detail view of the arm and a portion of the, scale dial;

Fig. 3 is a view of a portion of the dial showing the arm in itsnormal position;

Fig. 4 is an enlarged section along the line H of Fig. 3,

Fig. 5 is 'a longitudinal section along the line 55 of Fig. 3, and

Fig. 6 is an enlarged detail view of the upper part of the indicating arm.

In carrying out my invention, I may make use of any of a number of forms of computing scales, of the type in which a pivoted arm swings over an arc-shaped dial, the dial being provided with a series of concentric arcs, and the arm being provided with numerals corresponding to the arcs. he

dial also being provided with radial lines ad acent to said concentric arcs with numerals corresponding to said radial lines. These dials have a row of numerals at the top or bottom indicating the weight in pounds. 4 i

In Fig. l I have shown a scale of the type described, which comprises a base 1, a- 115118- ing 2 supported thereby, 3 a dial or cha t within the housing, a fulcrum or support t for the knife edge 5 of the pendulum 6. T, e arm which I have denoted in general by A is rigidly secured to the pendulum 6 so as to swing with it. An arm 7 is engaged by a link 8 carried by the scale beam 9. i i slidable weight is shown at 10, while the form and scale pan are shown at 11 and 12 respectively.

center is also the point 5. Extending transversely across the opening-15 is a series of cross bars 16, these cross bars preferably formed in arc-shape, the centers or" t. e arcs being the pivot point al iirranged to extend longitudinally with respect to the arm A and across the opening 15, are fine wires or strings 17, which may pass through the cross bars 16, as shown in Fig. 5, or be attached to them in any suitable manner. These fine, hairlilre strands are spaced equal distances apart. It will be noted iiat there are eight of these strands, and that strand at the extreme right in Figs. 1, 2, and 3, has an indicating mark adjacent to iton the arm, this mark being shown at 18. The distance between this mark 18 and the side 19 of the opening 15 is the same as the distance between the large numerals N which indicate pounds on the scale S of the dial 3. In the present instance, the distance between adjacent hairlike strandscorresponds to two ounces on the scale 8.

It will be observed that the cross bars 18 have numerals 2, 4, 6, etc, indicating two ounces, and also division marks 20, which subdivide the space between adjacent strands nto divisions which represent one ounce With the except-ion of the specific form or" units' or ipounds.

on the's'itlefi' g On the SidQzBdgBS of the arm A are numerals denoting-prices, these .numerals corresponding to the series of concentric linesgl son the dial 3.

In Fig.12 ati22 I have shown numerals which 'denotethe products of the weight I and selling, price, in other'words, the total cost ofthe article to the buyer. ;Since these numerals are well known, I have only indicated a few of'them in the drawing. The whole dial, however, should be supplied with numerals-which represent the products of these 'f g price per unit and the number of From the foregoing description of the various parts of the device, the operation thereof'may be readily understood.

. Let us assume that a salesman wishes to sell seven pounds of a commodityin a container whose tare weight he does not .know. The arm A of the scale, in its normal position, will take the position shown in Fig. 3,

in which the registering mark 18 and the hair strand to the right will register with 5' *t e zero mark on the scale S. The salesmanfirst puts the container 25, see Fig. 1, on

the scale pan 12, and this will mo e the arm A until a balance is-attained. Now by not;

ing the pbsition of' the registering-mark 18 with respect tothe scale S, the weight of the container in ounces may be read directly from the scale S. We will assume that the weight of the container is twelve ounces, or

three-quarters of a pound. Knowing that cents. This selling price is adjacent to one.

of the cross bars 16. The amount the customer is to be charged, to wit, $2.80, appears at the intersection of the cross bar and the hair strand which registers with the numeral 7 on the scale.

It will be observed that the tare weight of the container is given directly on the scale, without the necessity of counterbala-ncing the container. The hand A also gives the gross weight, so that the gross weight, the net weight, and the tare weight may be indicated during the weighing of the comser1es of transverse indicating members modity.

I claim 1.
